The present disclosure provides systems and methods for the continuous production of liposomes. An example method includes (a) mixing a solution of lipid and organic solvent from one or more containers to create an organic solvent-lipid solution, (b) providing the organic solvent-lipid solution to a first inlet of an injection port at a first flow rate, wherein the first inlet is in fluid communication with a first conduit, (c) providing an aqueous solution to a second inlet of the injection port at a second flow rate, wherein the second inlet is in fluid communication with a second conduit, wherein the first conduit is positioned concentrically within the second conduit at an outlet of the injection port, and wherein the first conduit extends through the outlet of the injection port, and (d) mixing the organic lipid solution and the aqueous solution to create a plurality of liposomes.
摘要:
The present teachings are directed toward an electrocatalytic cell including a barrier, having at least a first side and a second side opposite the first side, comprising a material permeable to oxygen ions and impermeable to at least C0 2 , CO, H, 2 H 2 0 and hydrocarbons, an electrical power supply in communication with the barrier, a catalyst adjacent the first side of the barrier, a supply of feedstock components in communication with the first side of the barrier, a supply of a carrier gas component in communication with the second side of the barrier; wherein the feedstock components contact the catalyst and react to form hydrocarbon- containing components and oxygen-containing components, and the electrical power supply biases the barrier to thereby conduct oxygen ions from the first side to the second side. Also presented are a device and methods for producing carbon nanotubes.
摘要:
Thermoplastic polyurethanes having an alternating sequence of hard and soft segments in which a nanostructured polyhedral oligomeric silsesquioxane diol is used as a chain extender to form a crystalline hard segment constituting SMPs. The polyurethanes are formed by reacting a polyol, a chain extender dihydroxyl-terminated POSS and a diisocyanate. The polyurethanes have multiple applications including for example, important for human health care, drug delivery matrices, superabsorbant hydrogels, coatings, adhesives, temperature and moisture sensors, etc.
摘要:
Agonist of vascular endothelial sphingosine-1-phosphate receptors are described. Compounds such as FTY720 can be phosphorylated by sphingosine kinase-2 into the phosphorylated forms which serve as sphingosine-1-phosphate receptor agonists. The vascular endothelial sphingosine-1-phosphate receptor agonists are employed in methods of treating a mammal for vascular permeability disorders and unwanted vascular endothelial cell apoptosis, and for the growth of new blood vessels. The sphingosine-1-phosphate receptor agonists can be used for the manufacture of a medicament for treating vascular permeability disorders and unwanted vascular endothelial cell apoptosis, and for the growth of new blood vessels.
摘要:
Disclosed is a method of inhibiting anandamide amidase in an individual or animal and novel inhibitors of anandamide amidase. The disclosed method and novel compounds can be used to reduce pain in an individual or animal suffering from pain, reducing nausea in an individual undergoing chemotherapy, for example cancer chemotherapy, suppressing appetite in an individual, reducing intraocular pressure in the eye of an individual or animal suffering from glaucoma and suppressing the immune system in an individual with an organ transplant.
摘要:
Novel polycyclic cannabinoid analogs are presented which have preferentially high affinities for the cannabinoid CB2 receptor sites. The improved receptor affinity makes these analogs therapeutically useful as medications in individuals and animals for treatment of pain, glaucoma, epilepsy, nausea associated with chemotherapy.
摘要:
An implant system and a method for controlling the natural and artificial microenvironments surrounding an implanted device using an artificial tissue system (ATS) and includes methods of diagnostic and testing related thereto. The ATS, among other things, induce better integration, function, and extended lifespan of the devices at the site of implantation. The ATS includes cells, such as naturally occurring, engineered, and/or artificial cells; matrices such as natural, engineered, artificial and/or hybrid matrices; tissue response modifiers (TRM); and/or cell response modifiers (CRM). The specific composition of the ATS is based on the nature of the tissue in which ATS-device combination is implanted and the nature of the implant device, as well as the required function and lifespan of the implanted device. Additionally, the ATS, as well as ATSdevice combinations can be utilized in vitro to aid in the design of improved ATS, devices and ATS-device combinations for in \>ivo uses.
摘要:
Novel tricyclic cannabinoid compounds are presented. Some of these compounds exhibit fluorescence properties. The fluorescent cannabinoid compounds are typically endogenously fluorescent. Some of these compounds, when administered in a therapeutically effective amount to an individual or animal, result in a sufficiently high level of that compound in the individual or animal to cause a physiological response. The physiological response useful to treat a number of physiological conditions.
